Have any of you heard of anyone ever using phase change material (PCM) "movable partitions" as a resiliency strategy to mitigate indoor overheating during a heat wave in passive buildings? You'd keep them stored in a basement or cool room, and deploy them into habitable spaces during the heat wave to keep the space cooler than the exterior... Read more

Air movement keeps occupants comfortable when it's warm, so cooling setpoints can be higher, and natural ventilation is a viable option even at higher temps and humidity.

Hi all,

As you know, the Carbon Leadership Forum has been busy in recent years growing the tent of discipline-based commitments for reducing embodied carbon. SE 2050 and MEP 2040 provide the platform and commitment for structural and MEP respectively, and there is now interest brewing for an additional commitment in support of civil... Read more

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

Hey there SDLs!

We're having a debate in our firm about whether we're at a tipping point to hire an in-house energy modeler - someone capable of doing an MEP-caliber energy model inside a design firm. I know some you have in-house energy modelers on staff and I'd love to hear your experiences:

- How did you know your firm was at a... Read more

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all. There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... Read more

Hi Leaders,

We've pulled together some highlights from each of the three half-day cross-network workshops that happened in October. This report captures the gist of each workshop:

Dear all,

For a specific existing building application, we are looking for a half inch insulating glazing unit, preferably with low-e coating. Based on my research, 5/8" seems to be doable (1/8" glass + 3/8" air gap + 1/8" glass) but I'm yet to find a viable 1/2" solution. Have you come across any on your projects? Thanks for your...

Dear Colleagues:

This is a request from AIA COTE Advocacy to sign another petition on behalf of your firm. I know it's incomprehensible that we have to do this, but we at AIA COTE Advocacy think the US Federal Emergency Management Agency's removal of the term "climate change" from all their strategic planning documents is evidence of an...

All,

We are collecting examples of buildings that involved electrification initiatives (building does not need to be all electric as long as largely electric). Please share your projects with us through this short survey. It will take 8-10min to complete.

The study will culminate into a report and best practices to advocate for... Read more

Hi All,

At the SCL Summit in November 2019, the Carbon Group discussed meeting in Q1 2019 to craft an action plan for measuring and voluntarily disclosing carbon emissions from our operations.   To kickoff that effort, we will be having an online meeting. 

If your company is already disclosing greenhouse emissions or if that's... Read more

Hi All! 

We have had a few multi-family projects consider this single package vertical unit with integrated ERV, but we haven't pulled the trigger for fear of the unknown. Our local engineers aren't sure how it actually performs and worry it may not meet code requirements for separation between exhaust and intake. Has anyone else used... Read more

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

The green building world’s most anticipated awards are almost here!

Within the confines of the BuildingGreen safe space, I wanted to share the Forced Labor in the Building Material Supply Chain Mitigation Framework I shared at the 3/1 First Friday Fika. The intent is for this document to become public, but we are working through some permissions and final editing logistics. The project was collaborative... Read more
